    Properties

    • Design: Hubs with DIN 916 radial set screw and integral dismounting groove.
    • Tempretaure range: -30° C to +110° C (-22° F to +230° F)
    • Tolerance: On the hub/shaft connection 0.01 to 0.08 mm.
    • Service life: These couplings have an infinite service life, and are maintenance free, if the technical ratings are not exceeded.
    • Material:
      • bellows are made of higly flexible high-grade stainless steel, bellow of the serie 0.5 is Tombac
      • hubs from aluminium
    • Speeds: Up to 20,000 rpm, in excess of 20,000 rpm available with balanced version.
    • Non-standard application: Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request.
    • Properties of Miniature Coupling model MK1:
      • backlash-free and torsionally rigid
      • compensates for 3-axis of misalignment
      • a mounting groove or flattening of the shaft is not required due to the integrated dismounting groove
      • low-cost design
      • low moment of inertia
